1. Introduction
The vulnerability of agricultural productivity to sudden shifts in
global climate associated with human emissions of greenhouse
gases poses a clear threat to the global food supply. As such, the
physical, or abiotic, implications for food security as a consequence
of warmer temperatures, rising carbon dioxide concentration
[CO2], erratic precipitation, extreme weather events, have been the
subject of much research (Rosenzweig and Parry,1994; Lobell et al.,
2008; Wheller and von Braun, 2013; inter alia). Such research
efforts are of obvious necessity to quantify the vulnerability of the
food supply in the context of climate uncertainty; however, such
efforts do not always consider the role of rising [CO2] or climatic
change with respect to pest biology and the consequences for
agricultural productivity.
